Background

Overview

Understanding the direct and indirect impacts of global climate phenomena like El Niño on India's agriculture is crucial for disaster preparedness, developing climate-resilient farming strategies, ensuring food security planning, and maintaining macroeconomic stability.

El Niño, a climate pattern characterized by the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean, significantly influences global weather patterns. In India, it often leads to reduced monsoon rainfall and increased temperatures, severely impacting agricultural productivity and water resources.
